Entry/Exit Lighting

When you open any door, the lamps inside your vehicle will go on. These lamps will fade out 10 seconds after the last door is closed, or when the ignition is turned on after all doors have been closed. These lamps will also go on when you press the trunk release button, the unlock button or the horn button on the remote keyless entry transmitter.

The lamps inside of your vehicle will stay on for about 10 seconds after your key is removed from the ignition to provide an illuminated exit.

Dome Lamp

The switch on this lamp has three positions. The ON position will turn on the lamp. The DOOR position will turn on the lamp while a door is opened. The OFF position will shut off the lamp completely, even while a door is opened.

Trunk Lamp

The trunk lamp comes on when you open your trunk.

Battery Run-Down Protection

Your vehicle has a battery run-down protection feature designed to protect your vehicle's battery.

When any interior lamp (trunk, reading, footwell, visor vanity or glove box) is left on when the ignition is turned off, the battery run-down protection system will automatically shut the lamp(s) off after 20 minutes. This will avoid draining the battery.

To reactivate the interior lamps, do one of the following:

    • Turn on the ignition,
    • turn the exterior lamp control off and then on,
    • open a door,
    • press any remote keyless entry transmitter button (if equipped),
    • press the remote trunk release button, or
    • press the power door lock switch.

The battery run-down feature will also be activated when any door on the vehicle is left open and the ignition is in OFF.
